i IOWA Y BLASTER-CHAN NEL INSTALLATION FOR SCREEN GUIDES Application led January 16, 1928. Serial No. 247,172.

The object of my invention is to provide a plaster channel installation wherein screen guides may be mounted for movement towards or from the plaster wall in which the channel member is embedded.

More particularly it is my object to provide a guide having an attaching flange frictionally engaged with the plaster channel member wherein the guide may move towards or from the plaster channel member for either initial adjustment of the guide relative to the channel or for further adjustment in case of expansion or contraction of the buildin in which the channel members are mounted or for any other reason which necessitates adjustment of the channel member relative to the guide member and for enabling the guide member to be removed entirely when desired.

Vith these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in

which Figure l is a side view of a portion ofa wall with a window opening formed therein and my improved plaster channel installatlon members shown therein, parts being broken away and shown in section to better illustrat the construction.

Figure 2 is a central sectional vlew taken on the line 2-2 of Figure 1 showing the 1nstallation complete and substantlally enlarged. i

Figure 3 is a sectional perspective view of the lplaster channel member which is adapted to be embedded in the plastic material of the building.

Figure 4 is a perspective view of the gulde or track; and

Figure 5 is a sectional perspective view showing the guide channel member and screen in their relationship to the plaster wall in which the channel is embedded.

In the accompanying drawings I have used the reference character A to indicate generally a window opening formed in a wall 10.

V The wall 10 is covered with plastic material.

Within a recessed opening formed in the upper portion of the window opening, I place a screen box or casing 12 adapted to conceal a window screen 14 when the same is in rolled-up position. Upon the lower edge of the screen 14 I provide a binder 16 of relatively-sti material. Within the window opening A is mounted a steel easement window frame of any suitable kind and construction.

It is desirable to prov ide means for mounting guides upon the two sides of the window opening wherein the side edges of the screen 14 together with the outer ends of the binder 16 may be received and guided and for this purpose I provide guides or tracks B of substantially the shape and construction illustrated in Figure 4 of the drawings.

The position or distance'between the two guides B is adapted to be set or fixed by means of the binder 16. Any variation in distance between the two sides of the window opening A is compensated for by mounting the guides or tracks B in such a manner as to allow their adjustment towards or from each other and this is accomplished in the manner which 1 will now describe in detail.

Wit-hin the plastic material forming the wall 10, I embed a plaster channel member C. The plaster channel member C is formed of a single piece of material adapted to provide a pair of sides 20 and a back or bottom wall 22. The wall 22 is formed by outturning the inner edge of the walls 20 and then rebending them so as to provide outturned llanges 24 adjacent the walls 20.

Between the walls 20 and formed of the back material 22, I provide a track receiving flange 26. The track receiving flange 26 is formed by redoubling the material of the back 22 and inserting it or projecting it in between the two walls 20.

The entire plaster channel member C is adapted to be embedded in the plastic material of the wall 10 and the position thereof is clearly shown in Figure 2 of the drawings. The fianges 24 provide the recess anchor means for retaining the channel member C in proper position 1n its plastic material.

The outer edges of the walls 20 are rolled or outturned as at 28 so as to provide a neat .termed fastening anges.

curved edge which is arranged to be substantially flush with the outer wall of the plastic material. It follows that when the plaster channel member C is embedded in the plastic material, a channel or groove is provided within the plastic material for receiving the guide or track B.

The guide or track B shown in the accompanying drawings, is formed of a pair of similar sheets of material which are rolled or otherwise formed to provide a pair of spaced ianges 30. The flanges 30 may be properly The two pieces of material are brought together or inturned as at 32 for providing abutting surfaces 34. The abutting surfaces 34 are preferably spotwelded or otherwise fastened together.

Upon the free edge of theabutting surfaces 34 are provided outturned channel shaped parts 36 which form a guide for receiving the outer edge of the screen 14. The extreme outer edges of the portions 36 are provided with ilat spaced flanges 38 between which is received the screen 14.

The extreme upper ends of the guides B are inclined or cut-away as at 4() so that when the screen 14 for any unforeseen reason is pulled from its guides, the screen may pass up over the cut-away portions 40 into the casing 12 and then when the screen is again withdrawn the edges thereof will be received within the guide portions 36 of the track B.

The flanges 26 of the channel member C, after the plaster in which the channel member has been embedded is set, are designed to have the two anges of the track thereover. The flanges 30 and 26 frictionally coact with each other for retaining the guide member properly positioned relative to the channel member C.

When the track B is mounted upon the plaster channel member C it assumes the position as shown in Figures 2 and 5 of the drawings. The fastening flanges 30 are spaced a sufficient distance apart so that the member 26 when inserted between the flanges 30 will have the coacting surfaces frictionally contact with each other to the end that the guide or track B is frictionally mounted .upon and within the plaster channel member C.

The guides or tracks B are thus/mounted for adjustment towards or from the plaster channel member C. One position of the track B is shown in dotted lines in Figure 2 of the drawings and another position is shown by solid lines.

The frictional contact between the track B and channel member C is such'that when the parts assume a position, the particular position will remain unless something is done to positively readjust such position.

It will be noted that the entire track may be completely withdrawn when it is desired to paint the interior ofthe'building and that the portion 26 of the plaster channel is suficiently guarded by being projected a sufficient distance from the mouth of the channel member C as to preclude any paint from coming in contact therewith and thus possibly interfering with the easy operation of tion and arrangement' of the parts of my device without departing from the real spirit and purpose of my invention and it is m intention to cover by my claims, any mo itied forms of structure or use of mechanical equivalents, which may be reasonably ineluded within their scope.

ll claim as my invention: 1. lin combination with-a screen guide for roll screens, a plaster channel installation for said guide comprising side walls and a bottom wall, a guide receiving flange eX- tending from said bottom wall, said guide I having a channel shaped portion coacting with said flange whereby an adjustable joint results.
